From the mind of CJ Miller ...

Apple QuickTime is not a compression format, it is an open media framework supporting hundreds of codecs including mpeg, sorenson, and others designed for small file sizes. Unlike other media players, It also supports full bandwidth uncompressed files, for applications where preserving the original pixels is more important than file size. QuickTime is absolutely the most flexible, feature rich, and powerful authoring format available.

I opened one of the movies from the Eyemodule gallery in QuickTime Player and compressed it using the sorenson codec that is included for free with QuickTime. The file went from 3.5 mg to 300 K with a barely noticeable visual change. Then I made another version choosing a lower data rate and resulting in a file of 100 K with slightly more obvious compression artifacts. The important point here is that I chose whatever tradeoff between file size and visual quality that I want.

QuickTime is one of the key reasons I'm going to buy the Eyemodule2, as I don't want the camera making the compression choices for me.

Come on CJ, investigate the technology before you release any more pearls of wisdom that use crappy information.

So you downloaded the file to your PC,and then you can compress it more there. And the point of this is...?????
Your Visor is where the memory limitation is...not your computer. I say compress the video on the VISOR so you can fit MORE than you would normally.

Artifacts...? Oh come on. The video is 160x160 as it is. If you're worried about high-quality on that size of a video, you need help. I'd take a few compression glitches to fit more video, rather than a "perfect" 5 second 4 meg video.

The facts still stand.....the software that comes with the eyemodule 2 is not very nice with memory. The hardware is perfect, but they need to give some more options to the file formats that it saves in (JPG/MOV). I feel sorry for the Visor users that have only 2 megs to start with.

You're right, maybe next time I'll refrain from talking about Apple technology, considering there isn't much to talk about. Maybe someday that company will get ahead, without help from Microsoft.

Once again, you are wrong. The movies stored on the Visor are in a different (probably proprietary) format which are then converted to "raw" video during a hotsync. Going back in this thread you will notice that a 5 sec clip takes up only 1.1 MB of Visor memory. This is roughly 1/3 of the size of the uncompressed files. Even if the E2 converted the Visor files to MPEG on hotsync, they would still take up 1.1 MB of Visor memory.

The only thing you should refrain from doing is making un-informed jabs at things you have NO knowledge about. Regardless of whether you like Apple computers, Quicktime happens to be the best "media framework" out there. I use it daily and it allows me to work in formats ranging from broadcast quality to web movies, for fast or slow computers, on both Macs or PC's.

Yawn, an Apple v. Windoze flame war. Been there, done that. Actually, finding out that Eyemodule 2 uses QuickTime has bumped this from "Really Neat" to "OMG!, Me Want!!!!" status. The possibilities of Quicktime are endless, and combine that with the multimedia/movie capabilities built into EVERY new Mac makes for infinite ways to combine the images from an Eyemodule. And as for tech, I propose a test. I'll make a movie using the free movie creation software a Mac comes with and you make one with the free movie creation software your WIntel box comes with. Oh, wait.

Do files get embarrassed when they get unzipped?

Does anyone know if it's possible to use the EM as a webcam when pluged in the craddle ?
Would it even be possible ?

quicktime

in my experience quicktime & mpeg encoded movies of similar resolution, etc. are similar in resultant file size.

As an added note, however, quicktime clips seem to be of higher video quality than those produced by other encoding systems/codecs.

I think I remember this being touted as a reason to get a Palm V w/a wireless connection (via OmniSky) ... maybe a yr. or so back. So it's got to be at least theoretically possible. Not nec. w/EM's SW, though.

Cool Idea! The USB port should easily be able to handle the 640x480 stream going through it. Now we only need to have somebody come out with the pseudo conduit and drivers (that's the hard part)

I got my Eyemodule2 this weekend and posted some pictures (courtesy of iTools - this has to be the easiest way to make an album). The url is:

Thanks, Ken! I've been waiting for a glimpse of some non-showcase photos, and I'm still pretty impressed - it looks like em2 still has a little bit of trouble capturing high-contrast images (like http://homepage.mac.com/kepstein/.P..._08_41_10AM.jpg, but 640x480 will give Photoshop a lot more pixels to push around for adjustment.

The sunset shots with the blue snow in the foreground are great.

that's right... technically it would be possible...
However it takes a lot of coding to make it work...

Great pics... they look a lot better than the ones from the eyemodule 1....

How are the pics indoor in low lighting?

Hi ToolkiT,

Low light pics aren't too good. There's a lot of artifacts. I just took this one that shows the distortion.

BUT, it does do colors well..

talk about artifacts, that '7' is just a '2' upside down, the weirdest artifact I've ever seen

The thing that I find amusing is that you were out in the woods WITH YOUR VISOR! Could you get more geeky? (meaning that as a compliment of ocurse)
